title = "In vitro assessment of pressure recovery through St. Jude heart valve prostheses",
abstract = "Pressure recovery has recently been reported as a possible mechanism for the apparent overestimation of transvalvular pressure gradients by Doppler echocardiography across St. Jude heart valve prostheses when implanted in the aortic position. We have studied the effect of mitral and aortic configurations on downstream pressure recovery in different sized St. Jude valves. Pressure recovery in the central and side orifice was significantly higher for prostheses in the aortic position than for a mitral configuration (p<0.001). Pressure recovery in the side orifice was most effected by the downstream geometry which permitted the most accurate Doppler derived pressure gradients to be obtained in the mitral position across the side orifice (Doppler - catheter = 2.5±1.3 mmHg).",
